Abstract
A dry additive mixing system includes a dry additive dispenser, piping, a mix tank, and a controller. The dry additive dispenser includes a storage hopper, a weight batch hopper connected to the storage hopper, and a transfer auger configured to move dry additive from the storage hopper into the weight batch hopper. The piping is connected to the dry additive dispenser. The mix tank is connected to the piping. The controller is configured to control the transfer auger to move dry additive into the weight batch hopper until a target amount of dry additive in the weight batch hopper is reached, and selectively release the target amount of dry additive into the piping.
Claims20
A dry additive mixing system comprising:
- a dry additive dispenser including
- a storage hopper,
- a weight batch hopper connected to the storage hopper, and
- a transfer auger configured to move dry additive from the storage hopper into the weight batch hopper;
- piping connected to the dry additive dispenser;
- a mix tank connected to the piping;
- and
- a controller configured to
- control the transfer auger to move dry additive into the weight batch hopper until a target amount of dry additive in the weight batch hopper is reached, and
- selectively release the target amount of dry additive into the piping.
A dry additive mixing system comprising:
- a mix tank;
- a dry additive dispenser connected to the mix tank via piping, the dry additive dispenser being configured to dispense a dry additive into the piping;
- and
- a controller in communication with the dry additive dispenser, the controller being programmable to control the dry additive dispenser according to an admix water production program via an interface, wherein a user enters desired dry additive concentration values for one or more stages via the interface.
A method to produce admix water comprising:
- filling a mix tank with fluid via piping;
- measuring a target amount of dry additive;
- releasing the target amount of dry additive into the fluid;
- circulating the fluid and the target amount of dry additive through the piping and the mix tank to mix the target amount of dry additive into the fluid, which produces admix water;
- and
- releasing the admix water from the mix tank.
